On the evening of January 30, Liang Jianying, deputy general manager and chief engineer of CRRC Sifang Co., Ltd., landed on CCTV to &#8220;start&#8221; high-speed maglev. For the first time, Liang Jianying revealed the &#8220;hard core&#8221; technology behind the high-speed maglev and the exciting research and development story.<br \/>\nBoth the high-speed maglev train and the Fuxing EMU are masculine, tough and domineering. However, the total head length of the Fuxing EMU is 12 meters, while the total head length of the high-speed maglev train is 16 meters.<br \/>\nChief designer Liang Jianying introduced that the biggest difference between the two is that the tracked high-speed rail uses wheels to act on the track and contact the wheels to drive the train forward.<br \/>\nThe high-speed maglev train uses electromagnetic force to realize the non-contact suspension, drive and guidance between the train and the track.<br \/>\nSince the train is suspended in the air and does not need to touch the ground when traveling, its resistance only comes from the air and can achieve higher speed operation.<br \/>\nWhen the train is running at high speed, how to avoid air disturbance from affecting the safety of train operation and the riding experience in the train? Liang Jianying and his team designed a special test for this-a high-speed magnetic floating model test at a speed of 600 kilometers per hour.<br \/>\nAt the program site, Liang Jianying connected to the State Key Laboratory of Rail Transit to show everyone the test scene of two vehicles meeting at a speed of 600 kilometers per hour, which is a relative speed of 1200 kilometers per hour.<br \/>\nHowever, this whole experiment, which only takes one second, is not easy. Liang Jianying and the team took up to a year to prepare, and this problem was solved through trial and error.<br \/>\nIt is understood that the operating speed of high-speed maglev trains is defined as 400 kilometers to 600 kilometers per hour, which can effectively fill the speed gap between high-speed rail and aviation and boost the construction of my country&#8217;s three-dimensional transportation network.<br \/>\nWhen the high-speed maglev is put into operation, people can improve their time utilization and enjoy a more efficient, comfortable and safe new travel experience.<\/p>\n<div class=\"37c28470d9d6d3cb9ff74e663adb766a\" data-index=\"2\" style=\"float: none; margin:0px 0 0px 0; text-align:center;\">\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3594734025006597\"\r\n     crossorigin=\"anonymous\"><\/script>\n<\/div>\n\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>At present, CRRC Sifang Co., Ltd. has undertaken the research and development of my country&#8217;s&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[272],"tags":[],"class_list":["post-11541","post","type-post","status-publish","format-standard","hentry","category-today"],"_links":{"self":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/posts\/11541","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/comments?post=11541"}],"version-history":[{"count":0,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/posts\/11541\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/media?parent=11541"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/categories?post=11541"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.whatchina.cn\/wp-json\/wp\/v2\/tags?post=11541"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
